estimateNoise: Noise estimation

In ctlab/LinSeed: Linear Subpsace identification to solve complete gene expression deconvolution problem

Description

Estimates noise using multiple regression approach. Implements method described in J. M. Bioucas-Dias and J. M. P. Nascimento, "Hyperspectral Subspace Identification," in IEEE Transactions on Geoscience and Remote Sensing, vol. 46, no. 8, pp. 2435-2445, Aug. 2008.

Usage

estimateNoise(Y, noiseType = "additive", verbose = FALSE)

Arguments

Y	normalized gene expression data matrix, columns are genes and rows are samples
noiseType	character, describing noise type. Two possible values are "additive" and "possion"
verbose	logical, default value is FALSE

Details

Based on MATLAB original code from http://www.lx.it.pt/~bioucas/code.htm

Value

list with two elements, w – estimated noise and Rw estimated noise correlation matrix
